Lost Parcels: What to Tell the Customer

What to tell the customer about lost parcels comes down to three things: you are sorry, you have started a carrier investigation, and you will send a replacement or refund by a stated date. Customers worry less when they know what happens next.

Lost parcels are usually a delivery issue, but a replacement sent in the wrong size can turn into a return. A good size recommendation, as covered in AI size recommendation for fashion stores, helps the second parcel arrive right.

When is a parcel actually lost?

Don't declare it lost at the first missed delivery date. First check tracking, ask the customer to check neighbors and building reception, and look for a "delivered" scan without a parcel.

Carriers also have waiting periods. According to the USPS claims page, for lost mail the filing window starts at a minimum number of days after mailing, such as 15 to 60 days for Priority Mail and USPS Ground Advantage. Checked November 2026. Other carriers set their own rules.

What should the first reply say?

Reply the same day. Include:

1. An apology that is short and sincere.
2. What you already know from tracking.
3. What you are doing now.
4. A date for your next update.

Here is a template:

Hi [name], I'm sorry your order hasn't arrived. Tracking shows [status]. I've opened an investigation with the carrier, and I'll update you by [date]. If you prefer, I can send a replacement or refund now.

For more phrasing, see the guide to return emails that keep customers if you want a related tone.

Should you offer a replacement or a refund?

Offer both and let the customer choose, unless an item is out of stock. Customers who waited already feel let down, so don't make them wait for the carrier.

For made-to-order or limited items, say honestly how long a remake takes.

What does the carrier investigation involve?

You usually need the tracking number and the proof of value, such as an invoice or receipt. USPS lists a tracking or label number, proof of insurance and proof of value as required documents on its claims page.

Claims are not instant. USPS says decisions usually come within 5 to 10 days, per its claims information. Do not make the customer's refund depend on that.

How do you handle delays in a drop or sale?

Busy periods cause more lost and late parcels. Warn customers early, and use a standard update message. The guide on communicating delivery delays in fashion drops covers this.

If customers prefer a form to email, compare options in returns portal vs email returns.

What if the customer is angry?

Stay calm and specific. Repeat their problem back in one sentence so they know you read it, then move straight to the fix.

If the parcel held something for an event, such as a wedding outfit, ask about the date. You may be able to offer faster shipping on the replacement, or a refund so they can buy elsewhere. Let them decide.

Keep a record of the conversation in the order notes, so any colleague can continue without asking the customer to repeat themselves.

What should you avoid saying?

Some phrases make a worried customer angrier.

• "It's the carrier's fault." The customer bought from you.
• "Please wait another two weeks." Give a date you control instead.
• Silence. No update feels like no care.
• Vague promises. Say exactly what you will send and when.

What does an update schedule look like?

Set a rhythm and keep to it. For example, day one is the apology and the investigation. A few days later, send a short status update, even if nothing changed. When the carrier answers, send the outcome, plus the replacement tracking number if you sent one.

Use the same three-part message each time: what we know, what we are doing, when you will hear from us next.

What should you track internally?

Keep a simple log:

• Order number and tracking number.
• Date shipped and date of last scan.
• Date the claim was filed.
• Decision: replacement, refund or credit.
• Outcome of the claim.

Review it each month. If one route or carrier shows repeat problems, change it.

How can product pages prevent follow-up problems?

When a replacement goes out, you want it to fit the first time. A product page with clear photos, fit notes and a size guide supports that. See the product page checklist for fashion stores for a full list.

FAQs

How long should I wait before calling a parcel lost?

It depends on the carrier and service. Check your carrier's rules, and don't wait to reassure the customer in the meantime.

Should I ask the customer to file the carrier claim?

Usually not. You are the shipper and hold the receipt, so it is easier for you to file.

What if tracking says delivered but the customer says no?

Ask them to check around the address and with neighbors, then open a carrier investigation. Tell them what you are doing and when you will update them.

Do I need to refund before the claim is paid?

That is your policy choice. Many customers prefer a quick fix, so decide in advance how you will handle it.
